"Carou is a Hoopa and Mesprit fusion. While in his sealed form, his powers are limited, only being able to call part of his summons through the hoops.

When unbound, his powers are far vaster, being able to summon practicaly anything in a seemingly endless supply. But this is with the caveat that whatever is summoned must be desired by someone nearby

His Mesprit part makes him sensitive to the emotions of those around him. This is strengthened while unbound."
